The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
The SSD Review uses benchmark software called PCMark Vantage x64 HDD Suite to create testing scenarios that might be used in the typical user experience. There are eight tests in all and the tests performed record the speed of data movement in MB/s to which they are then given a numerical score after all of the tests are complete. The simulations are as follows:
- Windows Defender In Use
- Streaming Data from storage in games such as Alan Wake which allows for massive worlds and riveting non-stop action
- Importing digital photos into Windows Photo Gallery
- Starting the Vista Operating System
- Home Video editing with Movie Maker which can be very time consuming
- Media Center which can handle video recording, time shifting and streaming from Windows media center to an extender such as Xbox
- Cataloging a music library
- Starting applications
PCMARK VANTAGE RESULTS
PCMark Vantage gives us our first glimpse at real world performance. Overall the MyDigitalSSD BP5e Slim 7 Series reached 79K points, thus proving to be a fairly competitive product for realistic workloads. Most benchmark speeds here exceeded 300MB/s and reached up to 448MB/s in the Windows Vista start up benchmark and performance the worst in the Windows Media Player benchmark reaching 283MB/s.
For our last benchmark, we have decided to use PCMark 8 Extended Storage Workload in order to determine steady state throughput of the SSD. This software is the longest in our battery of tests and takes just under 18 hours per SSD. As this is a specialized component of PCMark 8 Professional, its final result is void of any colorful graphs or charts typical of the normal online results and deciphering the resulting excel file into an easily understood result takes several more hours.
There are 18 phases of testing throughout the entire run, 8 runs of the Degradation Phase, 5 runs of the Steady State Phase and 5 runs of the Recovery Phase. In each phase, several performance tests are run of 10 different software programs; Adobe After Effects, Illustrator, InDesign, Photoshop Heavy and Photoshop Light, Microsoft Excel, PowerPoint and Word, as well as Battlefield 3 and World of Warcraft to cover the gaming element.
- PRECONDITIONING -The entire SSD is filled twice sequentially with random data of a 128KB file size. The second run accounts for overprovisioning that would have escaped the first;
- DEGRADATION PHASE – The SSD is hit with random writes of between 4KB and 1MB for 10 minutes and then a single pass performance test is done of each application. The cycle is repeated 8 times, and with each time, the duration of random writes increases by 5 minutes;
- STEADY STATE PHASE – The drive is hit with random writes of between 4KB and 1MB for 45 minutes before each application is put through a performance test. This process is repeated 5 times;
- RECOVERY PHASE – The SSD is allowed to idle for 5 minutes before and between performance tests of all applications. This is repeated 5 times which accounts for garbage collection; and
- CLEANUP – The entire SSD is written with zero data at a write size of 128KB
In reading the results, the Degrade and Steady State phases represent heavy workload testing while the recovery phase represents typical consumer light workload testing.
As you can see, performance is recorded in terms of Bandwidth and Latency. Bandwidth (or throughput) represents the total throughput the drive is able to sustain during the tests during each phase. Latency, at least for the purposes of PCMark 8, takes on a different outlook and for this, we will term it ‘Total Storage Latency’. Typically, latency has been addressed as the time it takes for a command to be executed, or rather, the time from when the last command completed to the time that the next command started. This is shown below as ‘Average Latency’.
PCMark 8 provides a slightly different measurement, however, that we are terming as ‘Total Storage Latency’. This is represented as being the period from the time the last command was completed, until the time it took to complete the next task; the difference of course being that the execution of that task is included in ‘Total Storage Latency’. For both latency graphs, the same still exists where the lower the latency, the faster the responsiveness of the system will be. While both latency charts look very similar, the scale puts into perspective how just a few milliseconds can increase the length of time to complete multiple workloads.
For a more in-depth look into Latency, Bandwidth, and IOPS check out our primer article on them here.
AVERAGE BANDWIDTH (OR THROUGHPUT)
These results show the total average bandwidth across all tests in the 18 phases. In this graph the higher the result the better.
AVERAGE LATENCY (OR ACCESS TIME)
These results show the average access time during the workloads across all tests in the 18 phases. In this graph the lower the result the better.
TOTAL STORAGE LATENCY
These results show the total access time across all tests in the 18 phases. In this graph the lower the result the better.
Alright, here we are, looking at our PCMark 8 results, which are usually the breaking point of a product and gives us a much greater understanding about the SSD’s performance. PCMark 8 reveals some very good performance compared to that of the competition, even better than that of the OCZ Trion 100, which hardware wise seems to be identical to it. The BP5e Slim 7 Series is one of the best performing drives across the board too! In terms of latency, it is up there with one of the best mainstream SSDs, the Samsung 850 EVO and when looking at bandwidth, it is second to it only. Considering the fairly consistent performance in both the heavy and light workload phases on top, we are very impressed.
Thanks for this review! Adding real world file transfer and HD Tune, it makes the review complete for me. Finally a tlc drive that seems decent or actually good, almost on par with the 850 evo. Hopefully all tlc drives are heading in this direction. If the price is right I won’t be so negative about tlc drives. They need to up the warrantee to 3 years though. I think Toshiba makes the best nand besides Samsung. Why make larger ssds with slow write speeds it makes no sense because the bigger the drive, you’re going to use it for lager files transfers, backups, storage, so these 500-2000 gb tlc drives need faster write speeds. Who wants to transfer files from a fast operating system drive to a slow backup/storage drive? Not me and it seems like MyDigital agrees.
I think your award and generally your conclusion should be for the 960gb model and not the whole BP5e Slim 7 Series.
You haven’t tested the lower capacity models, and the performance is usually way worse, that’s why the send the bigger capacity models for reviews.
Don’t forget that the 240gb model has much smaller slc cache that it may even affect everydays performance since this is a tlc model.
Yes that is the case most of the time but the 240GB and 480GB also have wonderful performance.
